In TTML, the height of every line in a block is determined by lineHeight and fontSize style attributes, and should be the same for each line in that block, regardless of whether different sized text appears on different lines. Currently, a single PangoLayout is used to lay out all the text in a block; however, pango will vary the line height in a layout depending on the size of text used in each line, which is not compliant with TTML. This patch makes ttmlrender lay out the lines in a block itself, rather than using a PangoLayout to do the work. The code still uses a PangoLayout to render the text of each element, but the overall layout of the text in a block is now controlled by ttmlrender itself. By doing this, ttmlrender is able to ensure that the height of each line in a block is correct. https://bugzilla.gnome.org/show_bug.cgi?id=780402 |
